Mass/Shielding Anomaly Passive Detector Module


OBJECTIVE : Develop an innovative system to detect highly shielded special nuclear material (SNM) contained within Personally Owned Vehicles (POVs) through measurements of total mass, mass distribution, density, or whether it is high-Z material.

DESCRIPTION: Technology is sought to detect highly shielded special nuclear material within Personally Owned Vehicles (POV) at checkpoints, entry points, or inspections through the detection of anomalous dense masses. The proposed system should not use external sources of ionizing radiation. The technical approach will need the capability to sufficiently discriminate between potential threats and other dense masses to include, but not limited to, the engine block, fuel, and passengers contained within the POV. The sensitivity should be as such to detect anomalous dense masses in the nominal range of 50-500 kilograms. Approaches that utilize a single sensing approach or a fusion of multiple approaches are acceptable. In the proposal the following information should be provided: the technologies estimated performance in detection of mass anomalies in POVs with calculations and/or modeling, cost of implementation, and other implementation requirements such as estimated screening time. If the proposed technology provides the ability to further discriminate between various density classes such as high-z materials, then its estimated performance should also be provided. The intended use of this technology is a sensor component within a larger threat detection system that may also include radiation detection. However, the proposed system should not include radiation detectors unless radiation detectors are needed to demonstrate the goal of detection of mass anomalies.

PHASE I: Evaluate innovative technologies/components/system(s) and/or improved capabilities fusion that detect heavily shielded SNM. Phase I will determine the scientific, technical, and commercial merit and feasibility of the proposed approach. Quantification of feasibility shall be demonstrated through either validated predictive modeling or through laboratory level measurements of sensor sensitivity. The preliminary design will be reviewed to determine feasibility/viability and readiness to proceed to Phase II.

PHASE II: Evaluate the performance of potential system components leading to the best system design. The effort will then extend into building the subsystem and/or prototype so that its performance can be quantified. The approach should include system analysis that incorporates empirical laboratory measurements in a simulated operational setting to establish its effectiveness. During this Phase, the Offeror will engage with a number of potential end users to determine a range of performance requirements and translate those into evaluation criteria.

PHASE III: The prototype developed in Phase II shall be further developed to meet end user requirements and to be integrated into a full shielded SNM detection system. The prototype shall then be evaluated in a controlled operational environment to assess operational viability.
